A8M - Send V.8 Menu Signals; A8I: - Ci Signal Indication - Conexant H08-15355F Reference Manual

The ATD and ATA commands behave as specified in §6.3.1/V.25ter and §6.3.5/V.25ter, respectively, and +A8n indications
are not generated by the modem.
For subparameter values <v8o>=6 and <v8a>=5, the +A8I, +A8C, +A8A, +A8J, and +A8M indications are issued during the
course of the V.8 session to notify the DTE when the relevant V.8 signals are received. The modem controls the V.8 session,
however, and the +A8M command is not used.
Reporting Current or Selected Values
Command: +A8E?
Response: +A8E: <v8o>,<v8a>,<v8cf>[,<v8b>][,<cfrange>][,<protrange>]
Example: +A8E: 1,1,,1,"",""
Reporting Supported Range of Parameter Values
Command: +A8E=?
Response: +A8E: (<v8o> range),(<v8a> range), (maximum size of v8cf in octets), (<v8b> range),(<cfrange> option bit
range),(<protrange> option bit range)
Example: +A8E: (1,6),(1,5),(1),(0),(1,6),(1)

3.2.7.2 +A8M - Send V.8 Menu Signals

This command, applicable only in DTE-controlled V.8, directs the modem to send a V.8 CM or JM signal using the specified
hexadecimal coded string. If the modem can decode the menu octet string, and if it cannot implement a specified feature, the
modem reports an ERROR final result code, but stays in V.8 operation awaiting another command.
Syntax
+A8M=<hexadecimal coded CM or JM octet string>

3.2.7.3 +A8I: - CI Signal Indication

This indication is issued by an answering modem, if +A8E,<v8a>
recovered Call Function octet(s).
Indication Syntax
+A8I:<v8cf><CR>
Defined Values
<v8cf> A hexadecimal code octet representation of those Call Function octet(s). +A8I:0 indicates that the
modem timed out waiting for CI.
Example
+A8I:0 The modem timed out waiting for CI.
+A8I:X YYY
